The closest known relative of the Zanzibar servaline genet is
Lowe's servaline genet,
G. s. lowei, a subspecies which is found in the
Eastern Arc Mountains of mainland Tanzania. These two animals have presumably been evolving independently since at least the end of the last
ice age, when Unguja was separated from continental
Africa by
rising sea levels. The survival of the servaline genet on the island parallels that of the endemic
Zanzibar leopard, and the
Zanzibar red colobus. == Discovery and description ==
